UNEFIED SAW-SET TOQL.

Application filed March S0. 1922. Serial No. 5418,202.

To all whom it may concern.'

Be it known that I, NATHANIEL CovnLL, a citizen of the United States, residing at Tidioute, in the county of INarren and State of Pennsylvania, have invented a new and useful Saw-Set Tool, of which the following is a specication.

The primary object of my said invention resides in the provision of a saw set tool, wherein means are provided for permitting all of the saw teeth to be set to the same gauge, the saw being maintained firmly in place while each blow from the hammer is being delivered to certain of the saw teeth.

A further object is the provision of such a tool wherein unskilled workman may properly set rhis own saw, my tool being further characterized by the presence of what I term a hammer member, which is exactly the right size for the requirement of the saws to be set, which will effectively overcome the objection of striking more than one tooth, which is often times the case in setting saws.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure l-is an elevational view of a saw set tool, constructed in accordance with my invention.

Figure Q-is a top plan view thereof.

Figure 3-is 'a side elevational view,

partly in cross section.

Figure [is a perspective of the hammer member per se, comprising an essential part of my saw set, and

Figure -is a perspective of one of the gauge boards comprising my invention.

Referring to the drawings in detail, the numeral designates the main body of the saw set, which is in the form of a relatively elongated bar of any desirable material, preferably metal and carrying adjacent its upper end and upon the back side thereof,

a cross arm 2, the same being preferably set within a mortise 3 of the said body 1.

Adjacent the upper end of the rod constituting the body 1 are a pair of spaced forwardly extending ears or guide strips 4. between which are pivoted as at 5 an arm 6., the lower end of which carries a hammer T, the same consisting of a relatively hard material and being double ended as more clearly shown in Figure 4. This hammer 7 is secured to the end of the arm 6 by a set screw 8, passing through an opening 9 within the hammer, for permitting the same to be removed therefrom and reversed whenever oc casion demands. The said arm 6 carrying the hammer member 7 is normally forced away from the saw set body, through the instrumentality of a coiled spring 10.

Upon opposite sides of the bar 1 constituting the main body member of the saw set tool, are what I term gauge boards 11, the same being substantially l..-shaped as more clearly shown in Figure 5, and being formed with slots 12 by which they are vertically adjustably connected to the cross arm 2 by suitable securing means 13. As shown in the elevational view, Figure 3, the portion of the bar' 1 constituting the main body of the tool is reduced in thickness from its upper end to a point beneath the said gauge boards 11, and between these gauge boards and in alinement with the hammer member 7 is an insert 13 of hard steel, the upper edge thereof being bevelled for consequently setting the different saw teeth by striking the hammer member 7 thereagainst and bending these teeth over the bevelled edge of the said piece of steel.

For supporting my saw set tool, upon a convenient tree stump or log or any other piece of wood to serve as a foundation for the set, I have provided the bar 1, constituting the main body of the set with a pair of steel pins 14, the same adapted to bite into the support in an obvious manner.

Although I have herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein, without departing from the spirit and scope of the invent-ion as claimed.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent is:

1. In a saw set of the class described, a vertical bar constituting the main body of the saw set, a cross arm secured to said body and adjacent the upper end thereof, a pair of vertically adjustable gauge boards secured to the cross arm, a swinging hammer arm pivotally secured to the upper end of said bar constituting the main body member, and yieldable means for normally swinging the said hammer member away from said main body member, said yeldable means being interposed between the bar and the hammer arm beneath the pivot of the latter.

2. In a sauT set of the class described, a

. main body member in the form of an elongated vertical bar, a cross arm adjacent the upper end of said bar, a pair of vertically NATHANEL CUVELL.
